You would have to do 24.85 x 4 because the 24.85 is per hour and if someone is going for 4 hours, this is what we would have to work out. So it would equal: 99.40 miles per hour. :)
I wrote the domain and range in interval notation, not sure if that’s how you’re asked to do it. This is how I was taught to state the domain/range of a graph.
83 divided by 3.
Exact Form: 83/3
Decimal Form: 27.66666666. . .
Mixed Number Form: 27 2/3
<span> 2.632 x 10^4 ÷ 2 x 10-7 =
1.316 x 10^11
</span>
P = 10 + x + 2x + 7
= (10 + 7) + (x + 2x)
= 17 + 3x
Therefore, the perimeter is 17 + 3x feet.
